7 Commissioning
AL HPM
If there is no Isomix to generate the back-pressure, a simple manual valve (see Figure 7, valve 1), which is connected after
the HPM and serves as a throttle, can be used. We recommend that a pressure gauge is always provided after the HPM in
order to check the back-pressure generated.
We also recommend positioning the HPM inlet at least 200 mm lower than the tank outlet so that the fluid can flow freely into
the mixer. The circulation pipe return should be piped so that no air pockets can form in the pipes. The highest point should be
the Isomix or the product inlet in the tank (see Figure 7).
When connecting permanent pipes, it is also advisable to include a compensator in the pipe in some circumstances.
The barrier medium circuit must be filled with a suitable medium before commissioning the machine for the first time (see page
1817, Flush tank and axial face seal).
The machine may not be commissioned (even briefly) if the barrier medium circuit is not intact, otherwise the axial face seal
may be destroyed.

Brief test
Check the following again with a short trial run:
1. contamination in the funnel
2. set the valve on the funnel outlet to the closed position
3. the direction of rotation of the motor
4. the fluid level in the flush tank
5. check for any unusual mechanical noises
